Great stuff — and far greater still to come!

These optimal low radiation paths in, around, and thru Jupiter’s seething radioactive local space will be absolutely priceless when actual human beings get out there, I’d imagine.

PASADENA, Calif. — A NASA spacecraft has sent back the first pictures since arriving at Jupiter.

An image released Tuesday shows Jupiter surrounded by three of its four largest moons. The picture was taken on Saturday when the Juno spacecraft was circling 3 million miles away. Even at that distance, Jupiter’s Great Red Spot — a centuries-old atmospheric storm — was visible.

As far as the whole mind-to-computer thing I totally agree.

The name of the game, for me at least, when it comes to this type of thing is continuity of consciousness. Without that you are nothing more than a copy of another person, not the person themselves. That said, if there were to be a very, very slow process where your natural neurons are replaced by artificial ones, with both types working together seamlessly, THEN I’d be first in line.

The future looks bright, except when it doesn’t. Here are 10 exceptionally regrettable developments we can expect in the coming decades.

Listed in no particular order.

1. Virtually anyone will be able to create their own pandemic

Earlier this year, Oxford’s Global Priorities Project compiled a list of catastrophes that could kill off 10 percent or more of the human population. High on the list was a deliberately engineered pandemic, and the authors warned that it could happen in as few as five years.

The universal quantum gate to enable long distance communications with QC without degradation.

Scientists have now developed a universal quantum gate, which could become the key component in a quantum computer.

Light particles completely ignore each other. In order that these particles can nevertheless switch each other when processing quantum information, researchers at the Max Planck Institute of Quantum Optics in Garching have now developed a universal quantum gate. Quantum gates are essential elements of a quantum computer. Switching them with photons, i.e. light particles, would have practical advantages over operating them with other carriers of quantum information.

The light-saber fights of the Jedi and Sith in the Star Wars saga may well suggest something different, but light beams do not notice each other. No matter how high their intensity, they cut through each other without hindrance. When individual light particles meet, as is necessary for some applications of quantum information technology, nothing at all happens. Photons can therefore not switch each other just like that, as would have to be the case if one wanted to use them to operate a quantum gate, the elementary computing unit of a quantum computer.

Why synthetic diamonds are critical to the QC story.

(Phys.org)—By carefully placing a tiny piece of diamond within a few nanometers of a carbon nanotube, and then sending an electric current through the nanotube, researchers have designed a device that could one day form the building blocks of quantum information processing systems. In their recent study, they have shown that the electrified nanotube’s mechanical vibrations couple to the magnetic (or spin) properties of defects in the diamond. This coupling allows for the quantum states of the nanotube and diamond to be transferred to each other as well as to a second diamond positioned several micrometers away.

The researchers, Peng-Bo Li et al., have published a paper on the new hybrid quantum device in a recent issue of Physical Review Letters.

Diamonds and carbon nanotubes, which are both carbon allotropes, each have their own unique properties that make building such a device possible. Diamond contains defects called nitrogen-vacancy centers that emit highly coherent bright red light. The defects’ optical properties can be well-controlled so that they occupy one of two distinct states, which enables the defects to act as qubits. Carbon nanotubes, for their part, are well-known for their highly advantageous mechanical and electrical properties.

Physicists from New Zealand’s University of Otago have used steerable ‘optical tweezers’ to split minute clouds of ultracold atoms and slowly smash them together to directly observe a key theoretical principle of quantum mechanics.

The principle, known as Pauli Exclusion, places fundamental constraints on the behavior of groups of identical particles and underpins the structure and stability of atoms as well as the mechanical, electrical, magnetic and chemical properties of almost all materials.

Otago Physics researcher Associate Professor Niels Kjærgaard led the research, which is newly published in the prestigious journal Nature Communications (“Multiple scattering dynamics of fermions at an isolated p-wave resonance”).

Citing increasing U.S. launch costs and the “fleeing” of commercial customers to foreign launch service providers, the Defense Advanced Research Projects Agency (DARPA) is continuing to push a bold strategy tied to a new, reusable spaceplane that the Agency envisions flying 10 times in 10 days for a cost of less than $5 million USD per flight.
